Vampires are legendary creatures said to feed on the blood of humans and animals. It is difficult to make a single, definitive description of the folkloric vampire, although they were usually reported as bloated in appearance, ruddy, purplish, or dark in color. They are shapeshifters and can take many forms, predominantly bats or humans. Vampires are typically described as the undead, although some cultures believe that they can be living. Beginning in the 19th century, modern fiction began to portray vampires as gaunt and pale. In the past, vampire superstition in Europe led to mass hysteria, which resulted in corpses being staked and people being accused of vampirism. Many violent killing sprees have been attributed to vampires. They are known to terrorize their previous neighborhoods and will seduce their victims, waiting for the right moment to attack the neck. The creatures will frequently visit their relatives, particularly their spouses. Vampires are masters of disguise and camouflage. The most recently recorded case of vampirism is that of nineteen-year-old Mercy Brown, who died in Exeter, Rhode Island in 1892.
